Steve Parish, the club's chairman, added that he has been stunned by the figures he has seen other clubs spend in the transfer market.

"What's returned to football are the big-money owners, the win?at?all?costs owners, almost bottomless pockets," he said.

"I'd love to see how it all fits with Financial Fair Play, by the way, because I just can't see how half of this fits with that because the revenue of the clubs hasn't grown this year.

"I'm not accusing people of anything. I just don't understand the numbers - for some of the clubs - that they're spending, that are being quoted and how you can make that fit over a period with Financial Fair Play."

Palace have lost their opening two games of the season, to Huddersfield Town and Liverpool, without scoring.
